I just bought an injen cold air intake for my 99 civic ex. Should I be freaked out about water intrusion? If I do get water in my engine, what do I do? Thanx

 

In 99% of the cases you should not worry. You will need to worry if your actual filter becomes submerged. My advice would be to try to avoid puddles(floods) if you can. No car should be driven through these anyways. If you really are worried, many manufacturers are make bypass valves that will fit the Injen intake.
